This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-40 in place of this model. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X800-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40
The AirTAC SIJ200X800-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 800mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 760-800mm extension window. It delivers 15708N push and 15080N pull at 0.5MPa, features a Ø40mm rod, M36x2 thread, G3/4 port, and 50mm adjustable cushions. This SKU lacks a magnet (-S) and cannot accept a magnetic switch.
The exact drop-in replacement is the SAIJ200X800-40, matching the ISO 15552 interface, bore, force, port, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~9425N (60% of the 0.5MPa push), allowing a vertical lift of ~801kg with a 2:1 margin. The stop screw sets end position only; it is not a load lock. For load holding without live air, use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X800-40 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAIJ200X800-40 produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40 Is Used
Heavy Press Tonnage
Provides 28274N push at 0.9MPa for large press operations, with the 40mm stop screw allowing precise final position tuning of the 800mm extend stroke.
Pallet Positioning
Ideal for shifting heavy 801kg vertical loads with a 2:1 safety margin, where the adjustable end-stop accommodates varying pallet heights without re-plumbing.
Large Mold Handling
Moves substantial industrial tooling using the G3/4 port and 50mm cushions to decelerate smoothly, while the external stop dials in the exact 760-800mm extension.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40 with the SAIJ200X800-40
To replace the discontinued SIJ200X800-40, order the drop-in SAIJ200X800-40, reusing your existing FA, LB, or TC ISO 15552 mounts. The 40mm adjust window lets you tune the extend end-position from 760 to 800mm on-site. If sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore provides 21991N push at 0.7MPa. This non-magnetic SKU cannot take a switch; for sensing, select an SAIJ-S model (compatible with legacy CS1-B/DS1-B sensors). Because the 800mm stroke is long, use external guides to prevent rod bending and side loads. The stop screw is not a lock; for held loads, use a pilot-operated check valve or SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-40 FAQ
Yes, the SIJ200X800-40 is discontinued. The exact drop-in replacement is the SAIJ200X800-40. It shares the same ISO 15552 interface, 200mm bore, 800mm stroke, 40mm adjust window, G3/4 port, and mounting. The SAIJ family adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The double-acting single-rod SIJ200X800-40 delivers 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N push at 0.9MPa, and a theoretical max of 3204kgf at 1.0MPa. The external stop screw provides a 40mm adjustable window, shortening the nominal 800mm extend stroke down to 760mm. The stop sets end position only and is not a load lock; use an external rod lock for held loads.
